Step 1: iPSC/ESC maintainance

day 0 ~ 1 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “mTeSR”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
dispase1g/l

Step 2: mesoderm 1

day 1 ~ 5

culture “adherent” human PSC in “mTeSR” for “4” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “4” days.

concentrationunit
BMP48.0e-5g/l

Ideally, “mesoderm” should be obtained at the end of culture.

Step 3: mesoderm 2

day 5 ~ 7

culture “adherent” human PSC in “StemPro” for “2” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
